Physical properties

Hardness: 6.5-7 (Mohs); Color: Multi-colored (red, green, brown, cream); Luster: Vitreous to waxy; Crystal Structure: Hexagonal (Cryptocrystalline); Cleavage: None/Conchoidal

Formation & geological history

Formed as a rhyolite or tuff through volcanic activity where silica-rich fluids precipitated to form circular orbicular structures. Primarily found in the Marovato region of Madagascar.

Uses & applications

Primarily used in jewelry, lapidary arts, metaphysical collecting, and as decorative cabochons or carvings.

Geological facts

Ocean Jasper is only found on the coast of Madagascar and can originally only be mined during low tide. The deposit was lost for decades before being rediscovered in 1999.

Field identification & locations

Identified by its distinctive 'orbicular' or 'poppy' circular patterns. Look for spherulitic inclusions and a variety of vibrant colors. Common in New Age shops and mineral shows.
